Hm, before going to the ultimate, I'd try to exclude some details before: not saying, a clean OSX install might not solve your issue, but when it fails, you're not only back at zero, but with a clean OSX install at maybe a lot of apps to re-install. So, OSX 10.8 "very sluggish": you could install the drivers but still the device (you console) was not found? Does it still read 'no cable'? I might be mistaken, but I think I heard this here before - just can't remember which thread it was... Anyway: if by any means possible (a friend, a colleague) try to get your hands on a Laptop or PC running windows (anything above XP should do): find out if the problem persists - this would clearly point to some serious issue with the card. If not, the problem would be Mac-wise. I am not familiar with the architecture of Macs, but if it's not too far off from Windows machines there should be a way to have a look at your drivers report, to see exactly when what was updated/changed. Is your IF-driver the latest for Mac?
